How does time travel happen?
How does time travel happen? According to NASA, time travel is possible, just not in the way you might expect. Albert Einstein's theory of relativity says time and motion are relative to each other, and nothing can go faster than the speed of light, which is 186,000 miles per second. Time travel happens through what's called “time dilation.”
Do wormholes exist?
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
How will we travel in 2050?
Hyperloops, supersonic jets and electric aircraft: Here's what transport could look like by 2050. E-bikes, scooters and now even cargo bikes are also helping travelers, commuters, and delivery drivers cover shorter distances in urban areas without needing a fossil fuel-powered vehicle.
